## 3.3.0 (2016-07-25)

### Bug fixes

Fix bug in tokenizing of regexp operator after a function declaration.

Fix parser crash when parsing an array pattern with a hole.

### New features

Implement check against complex argument lists in functions that
enable strict mode in ES7.

## 3.2.0 (2016-06-07)

### Bug fixes

Improve handling of lack of unicode regexp support in host
environment.

Properly reject shorthand properties whose name is a keyword.

Don't crash when the loose parser is called without options object.

### New features

Visitors created with `visit.make` now have their base as _prototype_,
rather than copying properties into a fresh object.

Make it possible to use `visit.ancestor` with a walk state.

## 3.1.0 (2016-04-18)

### Bug fixes

Fix issue where the loose parser created invalid TemplateElement nodes
for unclosed template literals.

Properly tokenize the division operator directly after a function
expression.

Allow trailing comma in destructuring arrays.

### New features

The walker now allows defining handlers for `CatchClause` nodes.

## 3.0.4 (2016-02-25)

### Fixes

Allow update expressions as left-hand-side of the ES7 exponential
operator.

## 3.0.2 (2016-02-10)

### Fixes

Fix bug that accidentally made `undefined` a reserved word when
parsing ES7.

## 3.0.0 (2016-02-10)

### Breaking changes

The default value of the `ecmaVersion` option is now 6 (used to be 5).

Support for comprehension syntax (which was dropped from the draft
spec) has been removed.

### Fixes

`let` and `yield` are now “contextual keywords”, meaning you can
mostly use them as identifiers in ES5 non-strict code.

A parenthesized class or function expression after `export default` is
now parsed correctly.

### New features

When `ecmaVersion` is set to 7, Acorn will parse the exponentiation
operator (`**`).

The identifier character ranges are now based on Unicode 8.0.0.

Plugins can now override the `raiseRecoverable` method to override the
way non-critical errors are handled.

## 2.7.0 (2016-01-04)

### Fixes

Stop allowing rest parameters in setters.

Make sure the loose parser always attaches a `local` property to
`ImportNamespaceSpecifier` nodes.

Disallow `y` rexexp flag in ES5.

Disallow `\00` and `\000` escapes in strict mode.

Raise an error when an import name is a reserved word.

## 2.6.4 (2015-11-12)

### Fixes

Fix crash in loose parser when parsing invalid object pattern.

### New features

Support plugins in the loose parser.

## 2.6.2 (2015-11-10)

### Fixes

Don't crash when no options object is passed.

## 2.6.0 (2015-11-09)

### Fixes

Add `await` as a reserved word in module sources.

Disallow `yield` in a parameter default value for a generator.

Forbid using a comma after a rest pattern in an array destructuring.

### New features

Support parsing stdin in command-line tool.

## 2.5.2 (2015-10-27)

### Fixes

Fix bug where the walker walked an exported `let` statement as an
expression.

## 2.5.0 (2015-10-27)

### Fixes

Fix tokenizer support in the command-line tool.

In the loose parser, don't allow non-string-literals as import
sources.

Stop allowing `new.target` outside of functions.

Remove legacy `guard` and `guardedHandler` properties from try nodes.

Stop allowing multiple `__proto__` properties on an object literal in
strict mode.

Don't allow rest parameters to be non-identifier patterns.

Check for duplicate paramter names in arrow functions.
